The Extralink DVP-740 is a highly efficient fiber optic welder equipped with a patented, multifunctional fibre holder. It can be used for single mode, multimode, DS, NZDS, Bending Loss Insensitive Fiber (G657), pigtails, subscriber cables and connectors and for SOC (Splice-On-Connector) fibres and cables. It has fully automatic digital centering to the core (PAS technology). It is equipped with a large, easy to read 4.3-inch colour LCD display. It offers the possibility of testing the strength of the weld after the welding operation. It allows to work at heights up to 5000 m.
The device is characterized by compact size and low weight, its size is about 40% smaller than traditional fiber optic welders. The innovative design guarantees shock and drop resistance. It has an automatic system check function, which makes sure that the welder is in proper condition. The reliable DVP 740 welder is extremely durable and has a trouble-free operation, so it will serve you for many years. It is equipped with a lithium rechargeable battery (6Ah), which allows you to perform up to 120 welding and sealing cycles in one charge cycle.
Outside the device, the standard set is included: Fiber Cleaver (guillotine), cable stripper, spare electrodes, charger, cooling tray, instruction manual and a box to transport the set.

The DVP-740 fiber optic welder is an industry classic successfully used by large fiber optic network operators. It guarantees compatibility with all possible fiber optic solutions available on the market today, but also with those that may appear in the future. It is characterized by durability, reliability and failure-free operation. It will therefore be an excellent choice, also with a view to the future.
The DVP-740 is an arc welding machine that connects the fiber optics after they have been melted. The device automatically centres the tips to the core. After welding, it tests its strength with 2 N.
